Frequently Asked Questions
Is MetaMask safe?
MetaMask is considered secure for most users when used properly. It encrypts your private keys on your device and never shares them online. However, it's crucial to protect your seed phrase and avoid phishing sites.
Which blockchains does MetaMask support?
By default, MetaMask supports Ethereum. However, users can manually add other networks like Binance Smart Chain, Polygon, Arbitrum, Avalanche, and many more.
Can I store Bitcoin in MetaMask?
MetaMask is primarily for Ethereum and Ethereum-compatible tokens. Bitcoin cannot be stored natively, but wrapped versions (e.g., wBTC) can be managed.
What happens if I lose my seed phrase?
If you lose your seed phrase, you lose access to your wallet permanently. There's no way to recover the wallet without it. Always store it securely and offline.
Can I use MetaMask on mobile?
Yes! MetaMask has a mobile app available for both Android and iOS. It syncs with your desktop wallet and provides full dApp access on the go.
